摘要
利用声压法对某直列六缸机的整机噪声进行测量分析,对整机噪声水平作出评价,确定了该机的主要噪声源位置,并为其降噪提供依据。
This paper analysed the noise of the inline six cylinders engine with sound pressure measurement,and evaluated the level of the whole engine noise, ensured the primary noise source.More methods of reducing noise of this engine were devised.
